Patented Aug. 20, 19h40 TAL FACEPLATES FOR THE LIKE PENKNIVES AND Maurice S. Share, Camillus, N. Y., assignor to` Camillus Cutlery Company, Inc.,.New York, N. Y., a corporation of New York VApplication January 22, 1940, Serial No. 315,131

4 Claims. (C l. 41-29)` This invention relates to the art of manufacturing ornamental faceplates primarily for penknives and the like and in which the faceplates are provided withf'one or more offset areas and With anrornamental coating applied to the remaining area thereof.

' yThe invention contemplates a method of manufacturing faceplates of the indicated character which utilizes mating die members having a punch and punch receiving recess for offsetting a portion of the plate and for simultaneously cutting out a portion of a masking sheet having a gummed surface and'causing the said portion to adhere tothe plate whereby upon removal of the remaining portion of the masking sheet a decorative coating may be applied to the unmasked portion of the plate; while the masked portion remains uncoated.

` More particularly the invention includes the steps of interposing a gummed' masking sheet or tape between die membershaving a punch and a mating' punch receiving recess respectively corresponding to the contour of the area of the faceplate to be offset, disposing a blank faceplate between the masking sheet and the adjacent die member with the gummed surface thereof disposed next to said plate, forcing said die members together to effect the offsetting of a portion of said plate and to cut out a corresponding portion of said masking sheet and press the gummed surface thereof into engagement with the offset portion, removing the remaining portion of said sheet from said plate and applying a decorative coating to the unmasked portion of said plate and 35 subsequently removing the cut-out portion from said plate.

With the above recited and other objects in view, the invention is set forth in greater detail in the following specification and illustrated in the accompanying drawing.

In the drawing:

Fig, 1 is an enlarged vertical sectional View through the offsetting die members and through the faceplate and masking sheet'illustrating the same in juxtaposition prior to the offsetting of the faceplate and the cutting out and applying of a portion of the masking sheet to the faceplate.

Fig. 2 is a similar view illustrating the step of 50 offsetting the faceplate and cutting out and adhesively bonding a portion of the masking sheet to the offset portion of the faceplate.

Figl 3 is a similar view illustrating the retracted relation of the die members after the olf- 55 setting operation and showing the cut-out portion of the masking sheet adhering to theoifset portion thereof. V y

Fig. 4 is a horizontal sectional view on a reduced scale taken approximately on lthe line 4-4 `of Fig. 1.

Fig, 5 is a sectional view on Van enlarged scale of the faceplate after the offsetting operation vwith the portion of the masking sheet applied to portion thereof.

Fig. 6 is a similar sectional view illustrating the finished faceplate with the coating applied and With the portion of the masking tape removed.

In carrying the method into practice, suitable oifsetting die members I 0 and II are employed, the latter being in the form of a xed block having an opening I2 extending vertically therethrough which may be of any desired cross sectionalshape corresponding to the contour of the offset portion to be produced on the faceplate I3. The lower terminal of the upper movable die member I0 has a cross sectional shape corresponding to the cross sectional configuration of the opening I2 and of slightlysmaller size. As illustrated, the lower die member or block .I I has arranged and tted within 4the opening I2 a yieldable elastic or resilient core I4, such as rubber or an equivalent material. The die member I0 may be operated in any suitable manner to advance the same towards and retract the same from the fixed die member II, such as by positioning the die members in a punch press.

In carrying out the method, a masking sheet I5 which is preferably in the form of a tape having an adhesive or gummed surface of a type which adheres upon contact and pressure is employed. In operation, the masking sheet or tape I5 with the adhesive or gummed surface disposed upward is fed between the upper and lower die members I0 and II as illustrated in Fig. 1 of the drawing. The face plate I3 is interposed `between the upper gummed or adhesive surface of the tape and the lower end of the upper die member. 'Ihe upper die member I0 is then forced downwardly, as illustrated in Fig. 2 to eiect the offsetting or embossing of a portion of the face plate as at I6. This simultaneously cuts out a corresponding portion I 'I of the masking tape or sheet I5 which is caused to adhere to the offset portion I 6 by virtue of the pressure exerted thereon as the yieldable core I 4 is depressed in the opening I2 of the lower xed die member H. When the upper die member I0 the coating operation, the portion l 'l of the mask-k ing sheet is removed thereby producing an ornamental face plate having a coated surface area I9 and an offset uncoated surface area IS.

For the purpose of illustrating the carrying n out of the method, the same is described for providing an ornamental face plate with a single offset area and a coated area surrounding rthe offset area and between the bolster ends I8 of the face plate. It is within the purview of the invention that one or more areas may be simultaneously offset, such as the offset area I5 and the bolster ends. i8 by utilizing appropriate die members and a sheet or strip of gummed masking tape of a width to accommodate the entire length of the face plate.

What is claimed is:

1. A method of -manufacturing ornamental face plates for penknives and the like including interposing a gummed masking sheet between offsetting die members, disposing a blank face plate between the gummed masking sheet and the adjacent die member with the gummed sur* face thereof disposed next to said plate, forcing said die members together to punchsaid sheet to produce an offsetportion therein andvcut out a portion of said masking sheet and press. the gummed surface ofa portion of said masking sheet into engagement with the plate, removing the unsecured portion of said sheet, applying a decorative coating to the unmaskedportion of the face of said plate vand subsequently removing the cut-out portion therefrom.
